The Rexroth pressure switch HED8 is a mechanical hydraulic pressure switch used to monitor system pressure and convert it into an electrical switching signal. It is designed for industrial hydraulic applications where accurate pressure detection, safety control, and reliable machine operation are required.

This pressure switch is commonly installed in hydraulic circuits to control machine sequences, trigger alarms, or protect equipment from over-pressure conditions.

How Rexroth Pressure Switch HED8 Works

The HED8 operates on a piston-based sensing principle. When hydraulic pressure reaches the preset value, the internal piston moves and activates a microswitch. This changes the electrical contact state and sends a signal to the control system.

The switching pressure can be adjusted manually, allowing the unit to be set according to specific system requirements.
